Digital infrared thermal imaging or thermography is a non-invasive, painless, no-contact, 100% safe screening process used in the early detection and monitoring of abnormal physiology and the establishment of risk factors for the development of cancer and other diseases. It uses an infrared camera to detect heat patterns and blood flow in all major organs, systems, and tissues of the body. The images generated from the infrared cameras are highly detailed and show heat and vascularity in the body that might indicate disease. This makes it easier for early detection and treatment of many types of abnormalities.
Although the FDA has approved thermograms for use, it has only approved them when they are used along with other screening methods or diagnostic tests such as mammography, not as standalone tools.
